Girth, length, width, area? Circumference Length Area?

The area of the rectangle is equal to the length and width.

The circumference is equal to (length and width) 2

Because the circumference is fixed, the wider the area of the rectangle, the larger it is. Because the face size of the rectangle is related to the difference between length and width, the smaller the difference between length and width, the larger the area, in other words, the closer the length of the width is to the length, the larger the area. Of course, it cannot be equal to the width, and if it is equal, it becomes a square, and the area of the square is the maximum.

For example, the circumference is 18 meters of two rectangles, 7 meters long, 2 meters wide, and an area of 14 square meters. It is 6 meters long and 3 meters wide, with an area of 18 square meters. 18 square meters is wider than 14 square meters, because 3 meters wide is longer than 2 meters wide, so the circumference is certain, and the wider the area of the rectangle, the wider it is related to the width.

The circumference of the rectangle is the length plus the width multiplied by the two, and the area is the length multiplied by the width so, 1The circumference of is (5+8)x2=26

The area is 5x8=40

2, to seek the width first, the width must do x, then find the value of x, 8 + x) x2 = 24Then the quotient divided by the multiplier equals another multiplier (8+x) = 24 divided by 2

8+x=12 The total minus one addition equals another addition, so x=12-8 x=4 width equals 4, and the area is length multiplied by width is 4x8=32

3.The area divided by the width is equal to the length 54 divided by 6 = 9, and the circumference of the length and width is multiplied by two according to the length and width.

4.In the same way as 3, divide the area by the length to get the width, and then calculate the perimeter.

5, the same as 2, first calculate the length in the calculation of the area.

Rectangle circumference = 2 * (length + width).

Rectangle area = length * width.

The area of the rectangle is calculated as: length and width = area of the rectangle.

Circumference = (length + width) x2

Area = length x width.

1: Circumference = 16 decimeters, area = 15 square decimeters.

2: Width = 4 meters, area = 32 square meters.

3: Length = 9 cm, circumference = 30 cm.

4: Width = 6 meters, circumference = 36 meters.

5: Length = 11 decimeters, area = 77 square decimeters.

The perimeter is equal to the sum of the lengths of all the lengths and widths, while the area is equal to the length multiplied by the width.

Rectangle area = length times width.

Rectangle circumference = 2 * (length + width).

Length, width, perimeter, area.

5 dm, 3 dm, 16 dm, 15 dm.

8m, 4m, 24m, 32m.

9 cm, 6 cm, 30 cm, 54 sq. cm.

12 meters, 6 meters, 36 meters, 72 square meters.

Circumference = (length + width) 2 Area = length and width.

2: Width = 4 meters, area = 32 square meters.

3: Length = 9 cm, circumference = 30 cm.

4: Width = 6 meters, circumference = 36 meters.

5: Length = 11 decimeters, area = 77 square decimeters.

Directly said that the perimeter length = area, is one-sided, and is calculated according to different shapes.

The side area of the cylinder = the height of the bottom circumference.

Rectangle area = length * width.

Square area = side length Side length.

Parallel quadruple square area = length and height.

Circular area = r.

It is often used to find the area of the figure on the reed branch, please refer to it.

Rectangle Area Formula.

Length and width. Rectangle Circumference Male Stare State = (Prepare Length + Width) Kai Roll Cover 2

Tao Tao and Xiao Xiao each used 6 square cards with a side length of 6 cm to spell a rectangle. The circumference of the rectangle they formed was 84 centimeters and 60 centimeters, respectively.

The calculation process is as follows:

There are two possibilities for a rectangle built by two people."

1. The circumference of the rectangle is: 2 (6 6 + 6) = 84 (cm) 2. The circumference of the rectangle is: 2 (6 3 + 6 2) = 60 (cm), so the circumference of the rectangle they put together is 84 cm and 60 cm respectively.

The length, width and height are xyz

Volume, Perimeter, Area, Side Area.

Rectangle x*y*z 2(x+y+z) 2(x*y+x*z+y*z) 2(x*z+y*z).

Square side length a a 3 6a 6a 2 4a 2 round ball s = 4 r 2 c = d r 2 hexagonal prism base area multiplied height six edges plus 12 sides 2 * base area + side area bottom edge * height * 6

The circumference is 5 decimeters, then the sum of length and width is decimeter, and the width is decimeter, then the length is decimeter, so its area is length multiplied by width, which is square decimeter.

Set the length x and the width y

1、l=2（x+y）

2、xy=s

If and only if x=y=root s, l has a minimum value.

lmin = 4 times the root number s.

Change the area to the perimeter, and the smaller to the larger.

For the same area, the closer the length and width are, the smaller the perimeter.

Rectangle: Area Width = Length.

Length and width) 2 = circumference.

Square: Area Width 4 = Circumference.

If it is a rectangle: first find the length = area width, then.

Circumference c = 2 * (length + width) = 2 * (area width + width) If it is a square: length = width.

Circumference c = 4 * width.

Length = Area Width.

After finding the length, the circumference = (length + width) 2

What is the area and perimeter? Prepare for auspiciousness.

Tu Shen talks about the wide hands and the round.

Area = length x width Width = area divided by length Perimeter = (length + width) x 2
